The Tsunehisa SW Washiji Difference

Tsunehisa knives are sourced from various blacksmiths and factories across Japan, offering high performance at an accessible price point - an ideal entry into the Japanese knife world. The SW Washiji series uses Swedish 19C27 stainless steel as its core - a pure, fine-grained steel prized for its edge-taking ability and corrosion resistance, with a stepped grind and tsuchime (hammered) finish that helps reduce food sticking to the blade. Thin but not fragile, this series is well-suited to both professional and home use. The petty knife is the Japanese utility knife - a compact, nimble blade for tasks that require precision: peeling, trimming, segmenting citrus, and fine prep work where a chef's knife is too large. At 135mm it is the most compact petty option, light in hand and easy to control.
